Technical Abstract: Fat bodies are a crucial source of energy for insect survival and reproduction. Differing types of fat body cells and amounts have been previously reported for southern green stink bug but clear supporting images are lacking. Further, in ongoing studies elucidating the ecology of southern green stink bug in the southern United States, additional types of fat body cells in the abdomen were observed that had not been previously reported, and findings are presented here. Four types of fat body cells were characterized based on appearance as: 1) cloudy, white, and oily; 2) spongy, white; 3) spongy, yellow; and 4) honeycomb. Amounts of fat body cells in abdomens were categorized as abundant, intermediate, and lean. This report improves the sole existing schematic of fat body cell types, presents an initial record and images relating to newly identified fat body cell types, and provides the first visuals depicting the amounts of fat body cells that can be encountered in adult southern green stink bugs. These findings are critical components in elucidating the biology and ecology of the southern green stink bug.
